IMPROVEMENT IN BOBBlN-HOLDERS FOR SPINNING.

Specification forming part of Letters Patent No. 50,240, dated October3, 1865.

To all whom t may concern:

Be it known that I, JOHN GoULn1NG,ot'the city and county of Worcester,and State of Massachusetts, have invented certain new and usefulImprovements in Bobbin-Holders; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming a part of thisspecification, in which- Figure l represents a spindle with mybobbinholder applied thereto; and Fig. 2 represents a longitudinalcentra-l section ot' a spindle, bob bin-holder, and bobbin.

In the drawings, A represents the spindle; B, the whirl around which theband runs to turn the spindle, O, a guide or stop to act in connectionwith the bolster or upper bearing of the spindle. D is a base or ringpiece, which in this instance is made to answer a twofold purpose-viz.,a bottom supportt'or the bobbin E and a fastener for the bobbin-holdingsprings a a.

The springs a a are made with a swell, b, near their centers, so thatwhen they are applied to the spindle they assume the form shown in Fig.l.

To prevent the bobbin from wabbling the springs should be so arranged asto hold the bobbin with equal pressure on all the sides. To this effectI prefer to place the springs symmetrically or equidistantly from eachother.

-As the point of the spindle is made tapering the springs a c arefastened to the spindle in a simple yet effective manner. The lower endsof the springs a a are stamped in the proper form, and are placed withinthe ring D, and the latter is then slipped down over the spindle untilit reaches the desired point, when it binds upon the spindle, and aslight blow is sufcientto fasten the ring D and springs c a in a secureposition, as indicated in the drawings. When the bobbin E is presseddown upon the rest or seat D it compresses the springs c a, as indicatedin Fig. 2, and so long as the bobbin remains in this position it is heldfrom turning upon the spindle by the springs a a,and yet, when desired,the bobbin can be readily removed.

The old method of securing the bobbin to the spindle consisted inwinding yarn upon the spindle and then driving the bobbin down over theyarn. This mode, besides being expensive, resulted in dama-ge to thebobbins and spindles. The bobbins were often split, while the spindleswere as often bent, especially in the operation of removing the bobbin,which had to be pulled or knocked off', both operations requiring muchforce.

To obviate the above objections, bobbins have been made with linings ofindia-rubber, which have been used to some extent: but there are seriousobjections to making bobbins in this way, since it requires considerablelabor and expense to iit the bobbins with rubber linings, while the oilused to lubricate the spindle is very liable to impair the rubber.

All of the above objections are entirely obviated by my invention. It issimple, durable, andcan be applied readily to the spindles now in use.One spring, a, could be made to answer the purpose, but I prefer two. l

Having described my improvements, what I claim as of my invention, anddesire to secure by Letters Patent, is-

The device herein described for holding bobbins upon spindles, the sameconsisting ot' two or more centrally-bulging springs, secured, asdescribed and shown, into a seat or base fitting the spindle.
